    Abstract: 188 Background: Hypophosphatemia is observed during sorafenib treatment. At the increased metabolic demand of the liver, hypophosphatemia is considered to be associated with a good clinical course. Hypophosphatemia associated with sorafenib treatment may also be a favorable event, but this has not yet been elucidated. The aim of this study was to evaluate the clinical significance of hypophosphatemia developing during sorafenib treatment for advanced hepatocellular carcinoma (HCC). Methods: The data of 41 advanced HCC patients (median age: 68 years, female/male: 4/37, HBs-Ag(+)/HCV-Ab(+):10/22) who received sorafenib treatment (800 mg, daily) for more than 30 days were reviewed. There were 27 and 14 patients with Child-Pugh class A and B. UICC stage II/III/IV was observed in 13/10 /18 patients. Clinical data, including those on the serum level of inorganic phosphate (IP), were collected before and after 30 days of sorafenib treatment. Overall survival time (OS) was calculated from the start of sorafenib treatment. The significance level was set at p 〈 0.05. Results: Mean serum IP level before sorafenib treatment was 3.2mg/dL (range 2.4-4.5). After 30 days treatment, IP level was decreased (mean 2.6mg/dL, range 1.3-3.9), compared to that at pre-treatment (p 〈 0.001). The patients in whom the serum IP was less than 2.4mg/dL at 30 days was assigned to the decreased IP group (N=14, mean IP 2.1mg/dL, range1.3-2.3). The decreased IP group showed a better prognosis (no event of death during the observation time) than the nondecreased IP group (MST 286 days, p=0.024). In the non-decreased IP group, the serum Alb (mean 3.6g/dL) and T.Bil (mean 0.8mg/dL) were worse after 30 days treatment (Alb 3.4g/dL p=0.007, T.Bil 1.1mg/dL p=0.037). However, deterioration of Alb (mean 3.7 vs. 3.6g/dL p=0.505) and T.Bil (mean 0.7 vs. 0.8mg/dL p=0.404) could be avoided in the decrease IP group. Conclusions: Hypophosphatemia occurring during sorafenib treatment for advanced HCC was associated with a favorable prognosis. The serum Alb and T.Bil levels were indicators of liver function and were preserved in patients with decreased serum levels of phosphate. No significant financial relationships to disclose.

    Abstract: 167 Background: In the diagnostic work-up of hepatocellular carcinoma (HCC), intratumoral enhancement in the arterial phase (IE) of dynamic computed tomography (CT) or magnetic resonance imaging (MRI) represents tumor viability. Although such IE has been known to disappear during the course of sorafenib therapy, the precise impact of decreased IE has not yet been elucidated. Therefore, we focused on the impact of decreased IE on the time-to-tumor progression (TTP) in HCC patients (pts) treated with sorafenib. Methods: The change in IEduring the course of sorafenib therapy was reviewed in 52advanced HCC patients treated between January 2004 and April 2010. decreased IE was defined as the disappearance of arterial enhancement to a level equal to or less than that of the surrounding cancer-free hepatic parenchyma on dynamic CT or MRI. Even if one of the HCC tumors in a patient showed decreased IE, that patient was regarded as showing decreased IE. The impact of the pretreatment variables, decreased IE, and adverse events on the TTP were evaluated by the log-rank test. The Cox proportional hazard model was used to determine the most significant variables related to TTP. Results: Of the 52 pts, 48 were males and 4 females, and the median age was 70.5 years. The Child-Pugh classification was A in 28 pts and B in 24 pts. HCV Ab positivity, HBs Ag positivity, and seronegativity for both were observed in 39 pts, 7 pts and 6 pts, respectively. Decreased IE was found in 23 patients. The median TTP was 114 days in all patients, 165 days in patients showing decreased IE, and 89 days in patients who did not show decreased IE. The median time to decreased IE was 41 days. In the univariate analysis, decreased IE, female, prothrombin time, and serum PIVKA II were identified as being significantly associated with the TTP. Multivariate analysis using the Cox proportional hazards model revealed decreased IE (p=0.04) and prothrombin time (p=0.04) to be independently associated with a favorable TTP. Conclusions: Decreased IE is correlated with a favorable time-to-tumor progression in HCC pts treated with sorafenib. No significant financial relationships to disclose.

    Abstract: 178 Background: Neutropenia is an important dose-limiting toxicity of gemcitabine (GEM) in patients with advanced pancreatic cancer (PC). Serum haptoglobin, regulated by pro-inflammatory cytokines, is a predictor of neutropenia in PC patients under treatment with GEM. We conducted this study with the aim of identifying the association between serum levels of haptoglobin and cytokines and the risk of development of neutropenia in advanced PC patients receiving GEM therapy. Methods: Serum levels of haptoglobin and pro-inflammatory cytokines (GM-CSF, IFN-γ, IL-1β, IL-2β, IL-6, IL-8, IL-10, IL-12, TNF-α) were measured in 55 patients with advanced PC. All patients (median age: 67 years, male/female: 26/29, ECOG performance status: 0/1/2: 32/21/2,) received GEM monotherapy as the initial treatment for PC. The severity of neutropenia within the first 90 days of the GEM treatment was graded according to the NCI Common Terminology Criteria for Adverse Events, version 3.0. Categorical or and noncategorical data were compared using Student's t test. Multivariate regression analysis was performed using logistic regression modeling. The significance level was set at p 〈 0.05. Results: Grade 0 to 2 (G0/1/2) and grade 3 to 4 (G3/4) neutropenia were observed in 32 patients (58.2%) and 23 patients (41.8%), respectively. The G3/4 neutropenia group showed low serum levels of haptoglobin (mean 144.4 mg/dl vs. 186.7 mg/dl, p=0.097), IL-1β (mean 0.07 pg/ml vs. 0.24 pg/ml, p=0.044), IL-6 (mean 1.13 pg/ml vs. 6.43 pg/ml, p=0.002), IL-8 (mean 18.4 pg/ml vs. 44.8 pg/ml, p=0.015), and TNF-α (mean 6.28 pg/ml vs. 8.86 pg/ml, p=0.017) as compared to the G0/1/2 neutropenia group. Multivariate analysis revealed that only low serum IL-6 was significantly associated with the development of G3/4 neutropenia (OR=0.081, p=0.0011). Conclusions: Low serum IL-6 level was associated with severe neutropenia. Thus, circulating IL- 6 levels may be a predictor of the development of severe neutropenia in advanced PC patients receiving GEM therapy. No significant financial relationships to disclose.

    Abstract: 183 Background: Alkaline phosphatase (ALP) is an enzyme that is elevated by various hepatobiliary diseases. Generally its elevation is thought to indicate bile stasis. There are some reports that show ALP is an important prognostic factor for several cancers such as colon, lung, and gastric cancer. Often it is speculated that ALP elevation indicates bile stasis caused by liver metastasis. However, the significance of ALP elevation in advanced pancreatic cancer (APC) patients is not well evaluated. The aim of this study was to determine the significance of elevated serum ALP as a prognostic factor in patients with APC even without jaundice and liver metastasis. Methods: Serum ALP levels were measured in 393 patients with APC receiving gemcitabine monotherapy before treatment, and according to those levels, patients were subgrouped (ALP 〈 upper normal limit (UNL), UNL-500 U/L, 501-700 U/L, 701-1000 U/L, 1000U/L 〈 ALP). The clinical data of each group were analyzed to see characteristics of elevated ALP patients. The relationship between ALP level and survival, response were also examined. Results: The elevated ALP group included poor performance status (PS 〉 1) patients (41.3%, p=0.001), and associated with low serum albumin (3.31±0.38, p 〈 0.01). The elevated ALP group (median survival time (MST) 112 days) showed significantly worse prognosis and lower disease control rate compared to the normal ALP group (MST 217days) (p 〈 0.001, p 〈 0.001). Multivariate analysis revealed ALP (p 〈 0.001), CRP (p 〈 0.001), ascites (p 〈 0.001), distant metastasis (p=0.003), white blood cell count (p=0.005), PS (p=0.020), AST (p=0.020), and ALT (p=0.020) were independent prognostic factors. Similar results were seen in liver metastasis free patients without jaundice. Conclusions: Elevated serum ALP level correlated with poor performance status and low serum albumin. ALP was also the independent prognostic factor in liver metastasis free APC patients without jaundice. No significant financial relationships to disclose.
